BACKGROUND

The expansion of the Internet and the World Wide Web (“web”) has given computer users the enhanced ability to listen to and to watch various different forms of media through their computers. This media can be in the form of audio music, music videos, television programs, sporting events or any other form of audio or video media that a user wishes to watch or listen to. As time evolved, users were able to take the music that was on that compact disc store it on their computers and listen to it locally. Web systems were developed which allowed a user log on to a network such as the Internet and, using a media player, either listen to specific media chosen from a group of media that a particular service has to offer or listen to an array of media offerings such as a radio station wherein different songs or other forms of media are combined to allow a user to listen to a group of songs in sequence, whether chosen by the user or by the operators of the network service. For example, such a service is Yahoo® Music. Many media players, services and other software tools enable media to be organized by a user or a service into playlists, which, as the name connotes, are groups or lists of media files or file identifiers that can be used to effect playback by a user in a sequence or other selected or random order. Further, once a playlist is created, a user may manipulate and edit the playlists freely. However, what is lacking in each of the currently available systems is a method in which a user may easily share or make publicly available created playlists wherein such public playlists are searchable by key input parameters. Further, the current art lacks a sophisticated method of creating a playlist searchable by user-defined descriptor information.

DETAILED DESCRIPTION

It should be understood at the outset that, although an illustrative implementation of one or more embodiments are provided below, the disclosed systems and/or methods may be implemented using any number of techniques, whether currently known or in existence. The disclosure should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but may be modified within the scope of the appended claims along with their full scope of equivalents.

In one embodiment, the present disclosure provides a method for making a playlist available to the public. In another embodiment, the present disclosure provides a method for creating a playlist comprising user-defined descriptor information, which can be entered as free form text or prose rather than pre-selected information like a static genre or short title. In another embodiment, the present disclosure provides a method for searching for such public playlists.

In one embodiment the ability to publish, create, and search for a playlist is facilitated by a media management program. In a further embodiment a user interface of such a media management program allows a user to publish and search for playlists. In other embodiments, non-media management applications, programs, and/or servers are capable of searching for such published playlists.

FIG. 3 depicts an exemplary system configuration supporting the ability to publish, create, and search for a playlist. As can be seen in FIG. 3 , the exemplary system configuration comprises a device 335 connected to a processor 300 associated with a user 330. Further embodiments contemplate multiple users each connected to the system configuration via a processor as depicted in FIG. 13 . In one embodiment, the device may comprise any type of computing device capable of rendering media files. In another embodiment, the processor 300 may be located on a computing device, which can be, by way of non-limiting example, a personal computer, cellular telephone, personal digital assistant, or a portable media player, or any other device now known or to become known capable of carrying out the features and functions described herein. As seen in FIG. 3 , the processor may comprise a media engine 305, a messaging program 310, digital rights management (drm) 325, media files 320, plug-in applications 315, and a local database 380 for storing information such as playlist information. In addition, through the internet 340, the processor 300 is connected to a media server 360, other programs and servers 370 and a messaging platform 365. The processor can comprise any combination of necessary components know to those skilled in the art in order to perform the functions described herein. Further depicted in FIG. 3 , the processor 300 is connected via the internet 340 to a playlist program 345, a playlist storage 355, a playlist index 375, webservices 350, a media server 360, messenger platform 365, and other programs and servers 370. In one embodiment, the playlist program 345 manages the exchange of information to and from the playlist storage 355. In one embodiment, the playlist storage 355 stores all related playlist information. For example, as depicted in FIG. 3 , the playlist storage stores playlist entries comprising user-defined descriptor information as further described herein. In one embodiment, the playlist index 375 stores a subset of the playlist information stored in the playlist storage 355 so that the processor 300 and/or other programs and servers 370 can easily and efficiently access the stored playlist information. In a further embodiment, only playlists which have been designated as public are stored in the playlist index 375. Thus, the playlist index 375 may be accessed when searching for public playlists. In one embodiment, the web services 350 provide efficient manner or way to access the playlist storage 355 and/or playlist index 375. In other embodiments, the webservices 350 may not be necessary to access the playlist storage 355 and/or a playlist index 375. In one embodiment, as depicted in FIG. 3 , other programs or servers 370 are capable of being connected to the web services 350 and/or internet 340. For example, in some embodiments, other programs or servers 370 can communicate with the playlist index 375, playlist program 345, and/or playlist storage 355 alone or independent of the processor 300 and/or media server 360. Thus, as depicted in FIG. 3 , playlists are searchable by any user, program, server, or any entity with an internet connection. In one aspect, the system configuration allows any other program and/or server 370, such as any non-media management program, to search for playlists and/or store created and/or published playlists for searching. For example, a user could search for playlists, i.e./e. access the playlist index and/or playlist storage, from a search tool found in a downloadable toolbar such as for example the downloadable Yahoo!® Toolbar. With reference to FIG. 3 , multiple variations and combinations of connections among the various components are contemplated. Furthermore, FIG. 3 is merely exemplary and not meant to limit the system configuration or architecture supporting the present disclosure in any way. Variations of the components and configurations know to those skilled in the art are contemplated.

The publishing of a playlist according to one embodiment of the present disclosure will now be discussed with reference to FIG. 1 that depicts an exemplary method of the present disclosure. In one embodiment, referring to FIG. 1 , first, the user creates 105 a playlist. This playlist can be created in any number of different ways (i.e., user created, criteria playlists, affinity playlists) as known in the art. In one embodiment, a playlist comprises at least one media file and/or media file identifier. In one embodiment, once the playlist is created or during playlist creation, a user is able to enter user-defined descriptor information with respect to the playlist. Unlike current published playlists available in the art, user-defined descriptor information permits a user to creatively enter free-form text, prose, tags or keywords that the user believes describe characteristics of or feelings or moods set by the user-published playlist. For example, present published playlists permit a user to identify a title, genre, and/or artist information for the playlist. This information is not entirely useful to a third party seeking to find a playlist for a specific purpose, environment, mood, concept, or task, for example. User-defined descriptor information of the present disclosure, as used herein, refers to any type of user-provided text, prose, tags, keywords and/or descriptors describing a user's understanding, perception and/or feelings toward, or the mood set by, a playlist, as opposed to the less descriptive associated metadata namely playlist title, or artist, genre, or media file title, which are static and while factual may not satisfactorily provide sufficient characteristic information. One exemplary embodiment of a user interface capable of receiving user-defined descriptor information is depicted in FIG. 2 . Referring to FIG. 2 , the user interface comprises a text field box 205 in which a user can enter user-defined descriptor information. In one embodiment, the user-defined descriptor information may comprise a playlist description as entered by the user. Then, by selecting a user input indicia, such as a button 230, the user can save the user-defined playlist information along with the playlist. For example, FIG. 5 depicts a text description box 205 comprising user-defined descriptor information. In FIG. 5 , the playlist description box 205 includes the user-defined descriptor information “playlist for while at work. Not ideal for working out.” In one embodiment, each time the playlist is accessed, the user-defined descriptor information also appears along with the playlist. In further embodiments, the user can edit the user-defined descriptor information as many times as the user desires. In another embodiment, the user-defined playlist information entered into the descriptive field box 205 is indexed or serialized along with the playlist information into a storable playlist entry as described in further detail herein.

Referring back to FIG. 1 once the playlist is created 105, a playlist entry is created. 110. In one embodiment, the playlist entry is created 105 by serializing the playlist information and user-defined descriptor information into a searchable playlist entry format. In one embodiment, playlist associated metadata may comprise metadata about the playlist itself such as the playlist name, date created, the duration of the playlist etc. Further, the playlist associated metadata may comprise metadata about each media file within the playlist such as the title of the media file, artist, and album, length, date of creation, and/or rating. In one embodiment, the searchable playlist entry format may comprise a series of searchable fields. For instance, an Extensible Markup Language (XML) file or an XML Shareable Playlist Format (XSPF) file structure. For example, XSPF standard comprises elements or fields such as title, annotation or comment, identity of the creator, info such as a Uniform Resource Identifier (URI) or Uniform Resource Locator (URL), canonical ID, image associated with the playlist, creation date, any licensing term, etc. Thus, in one embodiment, when a playlist is created 105, the playlist information and user-defined descriptor information is serialized into a searchable format.

FIG. 4 depicts an exemplary playlist entry 400 derived from a playlist as depicted in FIG. 5 . Referring to FIG. 5 , the exemplary playlist 505 entitled “Example Playlist” comprises five media files each listed by song title 510, artist name 515, an indicator 520 of whether the playlist is burnable to a cd or not, the genre 525 associated with the media file, the duration 530 of the particular media file, and a rating 535 associated with a media file. For example, the first media file 540 in the playlist 505 is entitled “Brick,” by the artist “Ben Folds Five” which has duration of four minutes and forty-eight seconds. Further, as can be seen in the user interface, the media file 540 is not burnable and is in the Modern Rock genre. Additionally, the playlist description text box 505 has been entered with user-defined descriptor information 505 corresponding to the playlist. Accordingly, the playlist entry corresponding to the playlist 505 can comprise some, all, or none of the information displayed in the user interface. Other, non-displayed information associated with the media files within the playlist may comprise the playlist entry.

Accordingly, FIG. 4 depicts an exemplary playlist entry corresponding to the playlist as depicted FIG. 5 . As can be seen in FIG. 4 , the exemplary playlist entry 400 comprises several fields 405-435. As depicted in FIG. 4 , one field 405 comprises a listing of all the titles associated with the media files in the playlist. As seen, field 405 lists: Brick, Amber, Grace, It Ends Tonight, and Only the Good Die Young. Accordingly, with reference to FIG. 5 , these are the same titles associated with the media files of the playlist 505. Similarly, another field 410 comprises a listing of all the artists associated with the media files in the playlist. As seen, field 405 lists: Ben Folds, 311, Jeff Buckley, All-American Rejects, and Billy Joel. Accordingly, with reference to FIG. 5 , these are the same artists associated with the media files of the playlist 505. Further, field 420 lists the name of the playlist creator, field 420 lists the name of the playlist, and field 430 lists the genre associated with each media file in the playlist. In further embodiments, the playlist entry comprises a field 425 comprising strings of text representing the user-defined descriptor information into the field description box 205 as depicted in FIG. 5 . For example, referring to FIG. 5 , the text field description box 205 contains the user-defined playlist information: “Playlist for while at work” and “Not ideal for working out.” As described herein, in one embodiment, the playlist application is capable of serializing the user-defined descriptor information entered into the box into a useful field of the playlist entry. In one embodiment, the field 425 may comprise some or all of the text entered into the text field description box 205. Thus, the playlist is searchable by user-defined descriptor information. As can be seen in FIG. 4 , field 425 comprises the text strings “Playlist for while at work” and “Not ideal for working out.” Further depicted in FIG. 4 , a field entry 435 may comprise pointers to the contents of the playlist and/or physically include the contents of the playlist. In a further embodiment a playlist field entry may comprise a playlist ID assigned and recognized among an online media service. Accordingly, in one embodiment, a user or entity is capable of searching the contents of the playlist entry. Thus, the user-defined descriptor information can be used to further enhance indexing and searching capabilities. It is noted that not all of the fields in the playlist entry may be capable of searching. In further embodiments, it may be desirable to indicate which types of fields are not preferred for searching such as the member's user name or profile name. Again, in one embodiment, the playlist entry can comprise any combination of field entries gathered from different sources. Thus, in one embodiment, the categorical aggregation of fields into a useful playlist entry allows for efficient playlist searching capabilities.

Referring back to FIG. 1 , once the playlist is created 105 and the playlist entry is created 110, the playlist entry is stored 115 in a playlist index and stored 120 in a playlist storage. In one embodiment, with reference to FIG. 3 , the playlist storage 345 stores the playlist entries. Thus, the playlist storage contains all playlist information. In one embodiment, the playlist index 375 stores a subset of the playlist entries stored in the playlist storage 355 so that the processor 300 and/or other programs and servers 370 can easily and efficiently access the stored playlist entries.

Turning back to FIG. 1 , in one embodiment, the user can elect to publish 125 a playlist. In one embodiment, when the playlist is selected as published 125, the playlist entry is updated within the playlist index 130 and within the playlist storage 135. Similarly, when a public playlist is elected to become private (not depicted), the playlist entry is updated within the playlist index 130 and within the playlist storage 135. In one embodiment, the playlist index 130 and/or playlist storage 135 are not updated simultaneously upon publication or privatization. Instead, the playlist index 130 and/or playlist storage 135 are updated upon a pre-determined time interval. In one embodiment, only public playlists are stored in the playlist index. Thus, by accessing the playlist index for searching a playlist, only published playlists are searchable.

Accordingly, in one embodiment, a user's playlist is by default considered private. Thus, a user must affirmatively choose to make a playlist public. In one embodiment, a user may choose to publish their playlist, for example, by clicking on a user input indicia such as a button or link. The user is preferably given the option of making the published playlist public, thus allowing other users to not only view the playlist but to listen to media listed in the playlist as well. In one embodiment, the published playlist can contain pointers that identify the network location(s) at which the media file resides or may be accessed (a pointer may comprise a URL or URI), metadata or actual media files, although preferably the playlist contains pointers to avoid the need to store multiple copies of the same media file on the network. Thus, a playlist can be made available to a user at any location by publishing the playlist. Thus, the ability to publish a playlist has the added benefit of making the playlist completely portable by being available to all users, as it will be residing on the media server or other user accessible location(s) on the network.

For example, referring to FIG. 2 , through an exemplary user interface, the user is able to select the public feature 210 that publishes the playlist. In one embodiment, selecting the public feature 210 causes a visual indictor to appear or highlighting or any other way of emphasizing and indicating that a particular playlist is public. For example, in FIG. 2 , the text of the public feature 210 “Make it public” becomes darken and bolded upon selection. Further, the user can select the private 235 feature at any point to remove the playlist from the public. Similar to selecting the public feature 210, selecting the private feature may cause a visual indictor to appear or highlighting or any other way of emphasizing and indicating that a particular playlist is private. Further, as depicted in FIG. 2 , a user can also email 220 a playlist, send 215 the playlist via an instant messaging application, or copy 225 the playlist as a URL to share with other users, for example by posting it on a blog or website. In a further embodiment, once a playlist is selected as public, it is published on a profile page which may or may not be incorporated into a media management program as described in further detail herein.

In one embodiment, the playlists are searchable through a user interface as depicted in FIG. 5 . As can be seen in FIG. 5 , the user interface comprises an area 560 for searching for playlists. In one exemplary embodiment, the area for searching 560 for playlists comprises a drop down menu 545 and a text field box 550. As can been seen in FIG. 5 , the user can select the “playlist” choice from the drop down menu 545, enter any search criteria into the text field box 550, and select search indicia such as a button 555 to trigger a search for at least one playlist associated with the search criteria. In one embodiment, the playlist program 345 as depicted in FIG. 3 can receive input criteria from a user 330 or other programs and services 370, reference the playlist entries and retrieve and return the appropriate results back to the user's processor 300 and/or other programs and servers 370. In one embodiment, the processor 300 and/or other programs and servers 370 can directly search the playlist index without use of the playlist program. In one embodiment, referring to FIG. 3 , when a search input for a playlist is received from the processor 300 and/or other programs and servers 370, it queries the playlist index 375 for matching playlists. In one embodiment, some or all of the information contained in a playlist entry is searchable. In other embodiments, playlist entry information may be included in the entry and used for display in the user interface, but may not be searchable. This could include the number of songs or media files in the playlist, the images associated with the songs in the playlist, the date the playlist was created and modified, and the genre names of the songs in the playlist. Any other associated playlist information may be used as a field entry and may or may not be searchable.

In one embodiment, the playlist search results are returned via a user interface which displays the resultant playlists. In one embodiment, the user interface may be incorporated in a media management program. For example, in FIG. 6 , a user can search for playlists by choosing the playlist parameter 605 from a drop down menu 545 and entering search criteria 610 into a text field box 550. Then, a user can select a button 555 to trigger a search for playlists associated with the search criteria.

In one embodiment, the search criteria are used look for matches against the content of all the playlist field entries. For example, if the search criterion 610 is for the term “working” as depicted in FIG. 6 , each playlist entry is referenced looking for the term “working.” For example, the term “working” may relate to playlists for a working environment or even return playlists for working out. In any event, the input criterion can search by any string of text representing any portion or entire concept, situation, event, and/or mood. In one embodiment, if any playlist field contains the term, the playlist will be returned to the searching entity. For example, a playlist will be returned if the term “working” is found in the playlist title field, user-defined descriptor information field, artist field, playlist title field, and/or genre field etc. It is important to note that in some embodiments, the playlists storage and playlist index are capable of storing playlist entries from multiple users and multiple sources. Thus, when a playlist search is triggered, a user or entity can search playlists created by any other user or source. Thus, the present disclosure allows users or entities to search for any playlist indexed and stored in the playlist storage and/or playlist index from any creator and from any source.

An exemplary embodiment of the returned results from a playlist search is depicted in FIG. 9 . As can be seen in FIG. 9 , in one embodiment, the playlists matching the search criteria are displayed in a scrollable area 905. As depicted in FIG. 9 , the results of the playlist search may be displayed in columnar format. In other embodiments, the results of the playlist search may be displayed in table format, in a menu, drop down list or any other suitable way. Further, area 905 comprises a list of each of the matching playlist 910, 915, 920, 925, 930, and 935. In one embodiment, as depicted in FIG. 9 , each playlist is numbered 815, listed by title 825, by the member and/or user 945 who created and/or owns the playlist, key artists 830, and number 835 of media files within the playlist. In a further embodiment, as depicted in FIG. 9 , a playlist may also have listed a description column 950. In one embodiment, the playlist description 950 column lists an excerpt of terms from the user-defined descriptor information text box associated with each playlist. For example, as shown in FIG. 9 , the second returned playlist 915 has descriptive terms such as “easy listening” and “mellow” and the third returned playlist 920 has description terms such as “not for working in groups.” Further, in cases where no user-defined descriptor information has been entered and associated with the returned playlist, those returned playlists will not display a description. For example, the first returned playlist 910 has a blank space in the description column 950. In other embodiments, the description column 950 may comprise a URL, URI, or a pointer that directs a user to the full user-defined descriptor information. In other embodiments, simply toggling over the terms in the description column 950 will cause the full description to appear as an enlarged text box.

In a further embodiment, a user can filter the returned playlist results. For example, as depicted in FIG. 9 , a drop down menu 940 filters the displayed results by displaying all of the results or some select portion of the displayed playlists. For example, the playlist results may be filtered according to popularity, recency, the identity of the associated members to show only friends' playlists, by usage rights (for example, to display playlists with only subscription content), and/or any identifiable associated playlist attribute such as artist, album or genre. In other embodiments, the filter parameters may be set through a variety of presets or through a preference menu. For example, a preset could be selected for only displaying returned playlists that have the artist matching the search criteria. Other combinations and variations of filter parameters as known to those skilled in the art are contemplated.

In some embodiments, the search criteria used to identify a playlist is highlighted or otherwise emphasized in the user interface. The search term may be highlighted or emphasized using a particular color, a box around the text, via an icon, or any other known method of highlighting or emphasizing text and/or graphics in a user interface. In one aspect, this allows a user to easily view which field or playlist attribute matched the search criteria. For example, referring FIG. 9 , since the search criteria 610 was the term “working”, the term is boxed wherever it appears in the returned playlist user interface. As depicted in FIG. 9 , the term “working” appears in the description column 950 of the third playlist “80's Music” 920, the fourth playlist ‘Working Tunes” 925, and the sixth playlist “High Energy” 935. Meaning, in one embodiment, each of these playlists has associated user-defined descriptor information comprising the term “working.” Also, the term is boxed in the title of the fourth playlist “Working Tunes” 925. Thus, in one embodiment, the user interface displays the search term for quick and easy reference.

In other embodiments, instead of highlighting or otherwise emphasizing the search term in the returned playlist display, the display may comprise a column or some type of indicator that indicates where the search term is located with respect to the returned playlist. For example, the indicator or column can indicate that the search term appears in the title of a media file within the playlist, or is a part of the user-defined descriptor information, and so on.

In one embodiment, the returned playlist results are displayed as media file identifiers such as URLs, URIs, or pointers that can direct a user to the location of the playlist and/or its contents. Thus, through the user interface as depicted in FIG. 9 , a user can select any of the returned playlists and/or the member name to further explore information associated with the playlist and/or member such as viewing and/or playing the playlist.

FIG. 10 depicts an exemplary user interface if the “High Energy” playlist 935 is selected from the returned playlist user interface depicted in FIG. 9 . As can be seen in FIG. 10 , the media files of the selected playlist 935 are listed in an area 1005. Area 1005 lists each media file in the playlist 935 by media file title 1015, artist 1020, and rating 1025. In a further embodiment, as depicted in FIG. 10 , a button 1030 allowing a user to add the media file to their local media file collection, a button 1010 allowing a user to play the media file, and a button 1035 allowing a user to purchase the media file and its associated price 1040 are also listed next to each media file of the playlist 915. In a further embodiment, as depicted in FIG. 10 , a description text box 205 corresponding to the selected playlist is displayed. As depicted in FIG. 10 , the description box 205 comprises user defined descriptor information 1045 “This was my playlist for working out at the gym . . . when I was going to the gym.” Thus, it can be seen that the search term “working” 610 appears the in the user defined descriptor information 1045 associated with the “High Energy” playlist 935.

In a further embodiment, the playlist program is capable of weighting the fields of a playlist in order to determine which playlists with fields matching the search criteria should be returned to the user or entity. For example, the artist name and media file title fields may be weighted more than the creator name field. Thus, a playlist is more likely to be returned if a search criterion is found in the artist name and/or media file name than if in the creator field. In other embodiments, conditional logic is used to determine whether a particular playlist is returned to a user. In other embodiments, a specific count of occurrences of an input criterion in a playlist entry is required in order for a playlist to be returned to a user. In further embodiments, what playlists are returned is based, in part, on affinity relationships. The playlist program can also use the popularity of a playlist as measured by the amount of time other users spend listening to it to influence relevancy by ranking popular playlists higher than unpopular playlists. Playlist size may also be used as part of relevancy to ensure that users who search get useful playlists returned to them. Many combinations and methods of selecting a playlist using search criteria known to those skilled in the art are contemplated.

In one embodiment, once a playlist is selected to be public, it is published on a profile page of a media management program. In another embodiment, a user's profile page is accessible outside the context of a media management program. Thus, in one embodiment, the profile page is accessible from any authorized internet source. In one aspect, a profile page comprises a page which collects and displays various information about a particular user. In one embodiment, all of a particular user's published playlists may be displayed on the user's profile page. FIG. 7 depicts an exemplary embodiment of a user profile page. As can be seen in FIG. 7 , the profile page comprises several areas 705, 725, 730, 740 for displaying various types of information about the user. For example, area 725 displays user-defined text that describes the user's musical interests and/or preferences. Further, area 730 displays users applied media file ratings organized by genre, album, and song, and photos of the user's highest-rated artists. Also, area 740 displays a user's listening preferences. As depicted in FIG. 7 , the user can edit each area as desired. In particular, area 705 displays a user's published playlists. As can be seen in area 705, two playlists 715, 720 are listed. The profile page may show the playlist titles 750, 745, along with information such as key artists (not depicted), the number of songs in the playlist (not depicted) and description information 755, 760. This description information 755, 760 may or may not be derived from the playlist's associated user-defined descriptor information. Further, a link 710 is provided so that all of the user's published playlist may be viewed.

An exemplary embodiment of a user interface displaying all of a user's published playlists is depicted in FIG. 8 . As can be seen in FIG. 8 , a user's published playlists are displayed in a scrollable area 810 and are listed by number 815, playlist title and a representative playlist image 825, key artists included in the playlist 830, and a number 835 of total media files within the particular playlist. For example, the first playlist displayed is entitled “Rock Songs” which has five total songs and “The Rolling Stones” and “U2” as the key artists. In one embodiment, the key artist 830 represents the more popular artists as defined by a user, an online music community, or via ratings within the particular playlist. In another embodiment, the key artist 830 represents the artists with the highest reoccurrence within the playlist. In a further embodiment, the area 810 may also comprise a column for listing user-defined descriptor information (not depicted). In a further embodiment, as depicted in FIG. 8 , a corresponding categorical menu area 850 comprises a playlist selection 840 which can be expanded 845 to show all playlists. Thus, area 850 allows for easy browsing of a user's playlists. In one embodiment, area 850 provides a visual indicator (not depicted) indicating whether a playlist is public or not. In one embodiment, the visual indicator may comprise highlighting the public playlists, adding a particular icon next to each public playlist, or subdividing the expanded menu 845 (not depicted) into public playlist and private playlists.

Further, in one embodiment, selecting the play 820 button next to each playlist will cause the playlist to be loaded and played by a media management program (such as media player like Yahoo!® Music Engine or MUSICMATCH). Through such a media management program, a user can further manage their playlists. In one embodiment, the following variations and features regarding managing and the collaborative playlist is controlled by the media management program. For example, a media management program's user interface may allow the user to stop, rewind, fast-forward, pause, and or/stop the playing of the playlist. In another embodiment, the user can copy the playlist and rearrange and/or delete media files to customize the playlist. It is contemplated that users will also be able to bookmark other users' playlists, enabling them to keep access to a playlist even as the creator of the playlist makes changes to it.

Providing access of a user's published playlist on a profile page allows users to further get to know other member's and browse their musical tastes. Any combination and other areas of information are contemplated. In one embodiment, users can control access to their playlists by making an individual playlist public or private, or by making the entire profile page public or private. It is contemplated that access to a user's playlist may be controlled by further detailed designations. For example, a user can designate that all playlists are only publicly available to a designated list of friends, other users, or specific online community such as a messenger community.

In one embodiment, the ability to share and view playlists among different users will be dependent on certain Digital Rights Management (DRM). In one embodiment, the playlists created and viewed by another user will contain sufficient DRM information to ensure that the user viewing the playlist has sufficient rights or a specific permission level to permit the user to experience the media contained in the playlist. In one embodiment, this function is controlled by the media management program.

In one embodiment, the ability of a user viewing and/or playing of another user's published playlist to access a media file and/or media file identifier is governed by a permission level. In one embodiment, the permission level may be triggered upon the user attempting to view the playlist. In another embodiment, the permission level may be triggered when the user attempts to play the playlist. Meaning, that in one embodiment, the user can view all playlists, but permission levels will control whether a user can play the media files within the published playlist. Thus, in one embodiment, the ability to view and/or play a media file and/or media file identifier in a published playlist may be governed by a permission level. In one exemplary embodiment, the permission level is associated with the media file. In another exemplary embodiment, the permission level is controlled by a subscription from a service provider. Rights and permissions can be managed by a DRM application or an associated media management application or media player or combination thereof.

In an exemplary embodiment, the permission level depends on each user's status as a subscriber or a non-subscriber to an on-demand-streaming media service (ODSMS). For example, if the user who has published a playlist is a subscriber and the user desiring to view and/or play the published playlist is also a subscriber, then the desiring user can have full access to each ODSMS media file identifier on the playlist. In another exemplary embodiment, if the user publishing the playlist is a subscriber to an ODSMS and the user desiring to view and/or play the published playlist is a non-subscriber, then the desiring user may have limited access to the ODSMS media files. For example, the desiring user may be limited to a pre-determined length clip of each ODSMS media file, such as a 30-second clip when the desiring user plays the media file. In another example, the desiring user may be given a pre-determined number of times the user can play each ODSMS media file. After this pre-determined number of times has been reached, the user is then limited to a default, pre-determined length of time for each media file (such as a 30-second clip). For example, the non-subscribing, desiring user may be limited to playing an ODSMS media file at its full-length to three times. Thus, once the user had played the media file and/or media file identifier three times, the user can now only listen to 30 second clips of the media file. This allows a non-subscribing desiring user to listen to ODSMS music otherwise not available to the user, while enticing the user to subscribe to the service. Accordingly, in one embodiment, once the user's pre-determined numbers of full-length plays are used, the user is prompted and has the option to subscribe to the ODSMS.

These embodiments are not limited to ODSMS media files, but can apply to any media files which require a specified level of sharing, viewing, and/or playing access. For example, it could be negotiated that certain media files generally not available for full-length sharing could be shared and played between any status (subscribing or non-subscribing) of users for a pre-determined number of times. For example, if there is a particular artist who wants to promote and/or entice users to listen to their media files, the artist or their representatives can allow a particular media file to be able to be viewed and/or played among any type of users. However, the users are limited to playing the media file to a certain number of times.

In another embodiment, the user can further utilize the collaborative playlist by burning the playlist to a compact disc (CD) or transferring the media files to a portable device. For example, the user can burn the media filed listed in playlist in the media player window to a CD and/or transfer the media files to a portable device by clicking a button and selecting the option from a drop-down menu. In some embodiments, the ability to transfer media files to a portable device or burn media files to a CD may depend on whether the user has specified access to those media files. Particularly, the user may be required to pay for files not located on the user's local media library. For example, the user may be required to pay for files located on an on-demand, streaming media service. Thus, the user may be required to pay a price for each media file before downloading or burning the media files. In another example, the user may be required to be subscriber to a service that allows the user to download and burn media files. In a further embodiment, the user can perform any of the above managing functions in any combination as the user desires using the media management program.

In a further embodiment, as depicted in FIG. 3 , other programs or applications and multiple users 370 can access the playlist program 345 and the playlist storage 355 to search for playlists from non-media management applications. For example, other Yahoo!® applications such as Yahoo!® Search could access the playlists and enable users to create, edit, and share playlists through the Search user interface.

In some embodiments, the playlist entries within the playlist storage 355 and/or playlist index 375 are updated with all of a user's newly created or edited playlists. In one embodiment, it is important to keep the playlist storage and/or playlist index currently updated with all the newly created playlists and any edits made to the existing playlists via a user's local processor. In one embodiment, synchronizing all playlist edits and newly created playlists among each user's local processor and the playlist storage and/or playlist index requires both that each playlist be associated with an easy identifiable ID and a technique for noting whether each particular playlist has been synchronized. For example, in one embodiment, once a playlist is created, it is associated with an id. In one embodiment, the ID is generated by an online media service. Thus, the playlist is recognizable throughout the service via its associated id. In further embodiments, other online communities or media services may have access to these playlist ids in order to catalogue, identify, and/or otherwise interface with the playlists by their associated id.

In one embodiment, the list of playlists and its associated ids are maintained in a database 380 stored on a user's local processor 300 as depicted in FIG. 3 . In one embodiment, the local database communicates with all of the components of the local processor 300 including the media engine 305. Further, in one embodiment, this local database 380 also maintains a status list or status table comprising each playlist, its associated id, and a flag, marker, or other type of identifier indicating whether that playlist has been fully updated with respect to the playlist storage 355 and/or playlist index 375. In one embodiment, the status table comprises only two states, updated and not-updated. In one embodiment, a playlist is considered not-updated if any type of edit has been made to a particular playlist, or a new playlist has been created and the playlist has not been synchronized with the playlist storage 355 and/or playlist index 375. Thus, the local media engine 305 can reference the database's status table to determine whether a particular playlist needs to be synchronized with playlist storage 355 and/or playlist index 375.

An exemplary synchronization process is depicted in FIG. 11 . An exemplary system architecture or configuration supporting the synchronization process of FIG. 11 is depicted in FIG. 3 . Referring to FIG. 11 , the synchronization process may be triggered 1105 based on a particular time interval such as every 15 minutes or every 30 minutes. In another embodiment, the synchronization process may be triggered 1105 by an event such as starting the playlist application. In yet another embodiment, the synchronization process may be triggered when the user changes any part of a playlist.

Once the process is triggered 1105, with reference to both FIG. 11 and FIG. 3 the local media engine 305 will request the local database 380 to upload to the playlist storage 355 and/or playlist index 375 any playlists that are flagged as not updated. In another embodiment, a playlist is flagged as updated when a user creates a new playlist or when the user modifies an existing playlist. If the upload is successful 1115, the local media engine 305 flags the each successfully uploaded playlists as updated. In one embodiment, if the upload is not successful 1120 or partially successful, each unsuccessfully uploaded playlist will remain flagged as not updated.

In some embodiments, multiple processors at different locations may be utilized by a single user and/or subscriber to an online media service. An exemplary system configuration comprising multiple processor ids depicted in FIG. 13 . As depicted in FIG. 13 , the system configuration has the same configuration and functionality as in FIG. 3 , however with an additional processor 1300 and user 1330. For example, a user may have a processor at home 300 and a processor 1300 at work and would like to access all updated playlists from each processor 300, 1300. Thus, it is desirable to further synchronize the edited playlists and any new playlists among each of the processors 300, 1300. In one embodiment, media server 360 and/or playlist storage 355 maintains a list of each user's processor wherein each processor is associated with an id. For example, with reference to FIG. 13 , processor 300 has an associate ID of “ABC” and processor 1300 has an associated ID of “DEF.” In a further embodiment, this list is maintained on the playlist program 345, and/or playlist index 375. In one embodiment, when a playlist is updated and uploaded to the media server 360 and/or playlist storage 355 as depicted in FIG. 13 , the media server 360 and/or playlist storage 355 will note which processor, via processor id, sent the uploaded playlists. Thus, the media server 360 and/or playlist storage 355 will know which processor ids have the uploaded and updated playlists and which processor ids do not have the uploaded and updated playlists. An exemplary synchronization process is depicted in FIG. 12 . An exemplary system architecture or configuration supporting such a synchronization process is depicted in FIG. 13 . It should be noted that this process applies to any number of processors and the descriptions are merely exemplary with respect to processor 1300. Further the actions performed by the processor 1300 as FIG. 12 and FIG. 13 can also be performed by the media engine 1305. Referring both to FIG. 12 and FIG. 13 , first, the synchronization process is triggered 1205. In one embodiment, the process may be trigged by a pre-determined, configurable time interval or by an event such as a user logging onto a processor. Once the process is triggered 1205, the local processor 1300 requests 1210 from the playlist storage 355 to download any newly edited or newly created playlists to the local processor 1300. Further, in one embodiment, this request 1210 may or may not be facilitated by the media server 360 and/or playlist program 345 as depicted in FIG. 13 .

Upon the request 1210, the playlist storage 355 and/or playlist index 375 references the requesting processor's 1300 ID to determine whether it already has the updated playlists. If the processor 1300 already has the updated playlists, then the playlist storage 355 and/or playlist index 375 will not need to download 1220 any information to the requesting processor 1300. If the processor 1300 does not have all the updated playlists, the playlist storage 355, and/or playlist index 375 sends 1225 a list of the playlist ids to be downloaded to the requesting processor 1300. In addition, when the list of playlist ids is downloaded to the requesting processor 1225, the local processor 1300 flags each downloaded playlist as not-updated. Thus, when appropriate, the local processor will synchronize the appropriate playlists as depicted in FIG. 11 and when successfully downloaded, will flag each playlist as updated.

Playlists are not limited to music files and can include other audio or video files. For example, this system could be used to build playlists of music videos or to develop playable lists of music, audio news, commentary, Really Simple Syndication (RSS) feeds, podcasts, still images, and video content. In a future application, users could be given tools to syndicate a playlist as an audio or video podcast.
